catalyzed arylation of dialkyl itaconate in presence of Pd(OAc)2/PPh3 as a catalyst, afforded trisubstituted olefins stereo selectively. These alkenes are useful intermediates for the synthesis of anthraquinone carboxylic acid derivatives. A new coumarin is also synthesized using this protocol.
摘要 在 Pd(OAc)2/PPh3 催化剂存在下,钯催化衣康酸二烷基酯芳基化,选择性地得到三取代的烯烃。这些烯烃是合成蒽醌羧酸衍生物的有用中间体。还使用该协议合成了一种新的香豆素。
